Answer:

$8\sqrt{2}$

Step-by-step explanation:

Solve7+x/4=5 For x please show steps

seraphim [82]

7 + x/4 = 5 (common denominator is 4)

4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)

4 *7 +4x/4 = 4 x 5

4 * 7 + x = 4 x 5

28 + x = 4 x 5

28 + x = 20 (subtract the 28)

x = 20 - 28

x = -8
